Apache Tomcat - HTTP Request Smuggling

Apache Tomcat from versions 8.5.0 to 8.5.93, 9.0.0-M1 to 9.0.81, 10.1.0-M1 to 10.1.13, and 11.0.0-M1 to 11.0.0-M11 contain an improper input validation caused by incorrect parsing of HTTP trailer headers, letting attackers craft headers to cause request smuggling, exploit requires sending malicio...

CVE-2026-40898

quic-go is an implementation of the QUIC protocol in Go. Prior to version 0.59.1, an attacker can cause excessive memory allocation in quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large trailer field section with many unique field...

CVE-2026-40898

CVE-2026-40898 affects quic-go prior to version 0.59.1, where a QPACK-encoded HEADERS frame can deplete memory by expanding into large trailer sections. This DoS affects both HTTP/3 servers and clients because trailers are decoded into http.Header, exceeding limits that were only enforced on the ...

CVE-2026-42310 Pillow: PDF Parsing Trailer Infinite Loop (DoS)

Pillow is a Python imaging library. From version 4.2.0 to before version 12.2.0, an attacker can supply a malicious PDF that causes the process to hang indefinitely, consuming 100% CPU and making the application unresponsive. This issue has been patched in version 12.2.0...

CVE-2026-42310

CVE-2026-42310 affects the Pillow Python imaging library. The vulnerability lies in the PdfParser logic: Pdf trailers’ Prev pointers can reference already-processed offsets, creating a cycle that causes an infinite loop and 100% CPU usage, potentially hanging the process. Affected versions are Pi...
